An alternative clutch master

[Dalamar]

So, this year I changed the clutch and the slave master started leaking. Refurbished the slave (kit BHM7063L) and fixed the leak. Next started to see black bits in the clutch master reservoir so refurbished that (kit SP2102). That was a fiddly job and a previous owner had swung on the pipe nut that connects to the master so hard that the bottom of the brass nut had flared!

All was fine for a while and then I noticed a few drips of fluid on my rubber car mats so I guess the master had some scores that I'd missed during the refurb.

Anyway, time for a new clutch master.

I looked around and most parts suppliers were selling them for around £60. Surely, there was a cheaper alternative from a decent supplier. The spec of the master cylinder is 0.70" bore with 7/16" UNF outlet port. The two holes are spaced 2-1/4" apart. The part is generally associated with the TR6 and the common part number is 64066117 or 154932 where you need to reuse your original pushrod.

I found a local supplier Moss Europe (https://www.moss-europe.co.uk) that sell them (TRW Brand) but I noticed that they also sold the left hand drive version 154933 or PMC133. I contacted Moss and the only difference was the length of the pushrod that I didn't need anyway. Price £29 or £34 delivered. I checked before buying that it had the 7/16" UNF outlet.

Here are some pics comparing the original to the new TRW unit.





So, new clutch master fitted and job done! Hope this info is useful.

Next job is those broken shock absorber bushes...
